Q. How do I access attributes of objects piped to other expressions?

A. When you use objects created out of expression output, you can access the object's individual attributes using the ($_.) syntax. This syntax is used in the following example, in which I list all processes using a working set of more than 100MB of memory. The command is

Notice that I accessed the passed object's working set attribute. (If you wonder why Microsoft Internet Explorer--IE--is using nearly 300MB of memory, it's because I'm watching the first season of Lost in HD from the ABC Web site as I write this. I've never seen it before and thought I would give it a go.)
